Great Guy James Cagney
My father worked in the studio system during the 1940's, and had a small speaking role during the recruiting office scene of this film. He could not say enough nice things about James Cagney, and what a nice guy he was during the filming. Cagney never went to a trailer between "takes." My father says he always mingled with all the workers on the set, kidding around and generally lightening up the mood.
It's just nice to know that such a talented actor was also a great guy.
